Symptomatic steno-occlusion in patients with acute cerebral infarction: prevalence, distribution, and functional outcome.

ABSTRACT:

Background and purpose

Symptomatic steno-occlusion (SYSO) in acute ischemic stroke has a significant impact on treatment options and prognosis. However, the prevalence, distribution, clinical characteristics, and outcome of SYSO are not well known.

Methods

We retrospectively identified 3,451 patients hospitalized because of ischemic stroke within 24 hours of symptom onset at 9 stroke centers in South Korea. Patients who did not undergo magnetic resonance imaging were excluded. SYSO was defined as stenosis or occlusion of cerebral arteries with relevant ischemic lesions in the corresponding arterial territory. The number, location, and severity of SYSOs and their effects on functional outcome were analyzed.

Results

In total, 1,929 of 3,057 subjects (63.1%) had SYSO. Th
